The display of secret blocks when embedded vs when shown under the secrets tab at the bottom of the article presentation screen is inconsistant. When embedded, the 'Visible to: (group name)' tag appears, while it is missing in the secrets tab. Screenshots below show the differences.
Adding the tag to the secrets displayed in the secrets tab makes the display of secrets more consistant.
perhaps it is a hick up in the system. i hope they can make it consistent without much work
